Re: [bmwg] New Version Notification for draft-lencse-bmwg-multiple-ip-addresses-00.txt

Hi Gabor,
	Thanks for the submission - I’ll review this week, and I invite the rest of the WG to do so as well.
	I will not be attending in person in Prague, although Giuseppe will be there, and I’ll be on the meet echo. I am sad that I’ll miss the chance to meet you in person! Have a wonderful first meeting; if there’s anything we can do for you to make your first meeting easier/better/more fun, please let us know. :)

Thank you,
Sarah
BMWG Co-Chair
